In other words, Alan tells the non-x86 folks that they can (in the words of
one of my favorite movies) "all line up and kiss his ass!" ROFL!

Oh, pretty please, DOCUMENT THE ASM CHANGES so we don't have to figure out
what the hell you did to fix it? I hate to be a pain in the ass and scream
yet again about kernel docs, but it really needs to be done if people want to
consider themselves professional programmers working on a system they want to
be accepted by the mainstream. It also makes porting code to other platforms
A LOT LESS PAINFUL. See, one of my clients is this really big hardware company
and I'd really like them to continue down the Linux road, but it's a tough sell
if the technical gang tells them that VxWorks or PsOS is a lot better because
they're designed to be relatively easy to port to other platforms.
